Corrupt DLC Problem

Have you tried deleting the DLC manually then reinstalling?

Go to "C:\Program Files (x86)\Origin Games\Mass Effect 3\BIOGame\DLC" and delete all the files and folders inside.

Restart Origin and redownload the DLC. This should correct the issue.

Yes, I've tried a clean re-install. I've even re-installed the Origin.

What DLC is it saying is corrupt?

If it's not telling you which DLC is corrupt, then you'd have to try going one by one.

Manually delete all the DLC in the ME3 folder (stated in my previous post), open origin, and install the first DLC, and try to run ME3.

If it works, great, download the next DLC. If it doesn't, make note of what DLC it is, delete it from the DLC folder, and try the next one.

Once you've done this, let us know which DLC it is that it is stating as corrupt so we can investigate further.

That's the problem. There is no DLC named under the error message.

After your response; I uninstalled ME 3 and Origin with uninstallers. deleted remaining folders, reg entries. Re-installed Origin and ME 3 and it looks like i have some troubles with multiplayer packs. When i added them to the download list and pause the downloads, then launched the game and got the same error again. By the way, I'm on Windows 8.

I have this very same problem. I have purchased The Mass Effect Trilogy set, installed successfully and all, but this error message keeps popping out on top of the main menu in Mass Effect 3. I've tried reinstalling mass effect 2 ( which had problem with my PhysX ) and Mass Effect 3 over again (4 disks, about an hour each. Mass Effect 1 worked just fine)  Mass Effect 3 also works just fine, but this DLC corrupted error message is getting on my nerve... I mean, What did I do?? I swear I own the legit copy T_T 

This Error is also persistent on me, I'm in windows 7 ☹️(

I have the same error occur when the game is starting up.  I went ahead and deleted everything in the DLC folder and then Mass Effect 3 would not start.  I had to repair the installation before I could get it started.

I have a friend who also plays Mass Effect 3 and we were going to play multiplayer.  Turned out all of the Multiplayer DLC packs were working fine despite the warning label.  When my friend tried to join my game it said she lacked the DLC to join, so I guess it was properly registered with my game and working fine.

Am running Windows 7 also.

I tried this, and now my Mass Effect wont start up. Thanks.

I am getting the same message.

Plus, I cannot follow Anderson off the buidling ledge, I just bounce back ☹️

In order to tell us at least one of many files is corrupted you have the scan each of the files one at a time.  Why can't you just tell us the name of the file that failed your scan, select it, prompt us to delete it and then restart the download automatically?

If that is to much programming to finish this app subroutine (based on your organizational priorities), then why not just tell us the path and the name so we can go delete it and possibly down load just one file(at least you would be providing a better solution)?

I have DSL, that means my download rate is 75KB/s available, if I dedicate all of my bandwidth to the repair of the DLC at the expense of all the other PC users at my house. 

I have spent many hours on the phone to get better service, but it is just not available! What you are asking me to do can take hours!

I think the answer to the question is inconsiderate of you customer base!

I'll see if I can come up with a better solution with W7 and constrained bandwidth...
